Open-source software is built on contributions from both volunteers and corporations, but an emerging body of research and commentary suggests that unpaid or underpaid contributors are often exploited to sustain enterprise-backed projects. Companies frequently benefit from community labor under the pretexts of "learning opportunities," "future job prospects," "developer prestige," or doing "service" for the community. Below, we examine evidence of this dynamic across major projects and foundations, and how ideological frameworks like meritocracy help justify the extraction of free labor.
